Abstract: A digital loop filter is used in a phase-tracking circuit which is adaptable to a phase-comparison radio navigation system such as the DECCA (registered trademark) system. The digital loop filter includes a feedback circuit which receives a digital input signal from the digital loop filter and outputs a digital output signal and which feeds back and adds the digital output signal to the digital input signal after a predetermined delay. It also includes a feed-forward circuit which multiplies the digital input signal by a predetermined constant (B) and adds the resultant signal to the digital output signal of the feedback circuit to generate a digital output signal. A multiplier for multiplying the digital output signal of the feed-forward circuit by a second predetermined constant (C) to generate a digital output signal of the digital loop filter is also provided.

Abstract: The invention disclosed shows a device, method and system for installing threaded masonry anchors. A plate is used to control the rate of axial penetration of the anchor into a masonry structure. An opening in the plate allows engagement of the anchor with the plate. Rotation of the plate is prevented by various means. As the anchor advances and forms threads in the structure, the plate may be used to resist axial forces on the anchor in either axial directions thereby precluding stripping of threads formed in the masonry structure.

Abstract: An improved memory management unit (MMU) for interfacing between a CPU and a main computer memory to convert logical addresses to physical addresses. The MMU's memory 20 provides sufficient capacity to permit relocation data and limit data to be stored for a plurality of processes, and thus, allows several programs to be run without reprogramming the MMU. Special "access" bits are also stored in the MMU's memory which, by way of example, prevent the writing into program, accessing of unselected processes or user access to certain memory locations to prevent, for instance, the copying of an operating system. <IMAGE>

Abstract: Band saw machines embodying this invention are especially adapted for cutting metal work pieces of extreme hardness and/or large cross-sectional size. The machines include a mechanism for oscillating or rocking the band saw relative to the work. The band saw is looped about an idler wheel and drive wheel spaced therefrom and a pair of spaced saw guide arms (20, 22) urge a span of the moving band saw (16) against the work (w). In one embodiment of the invention, an eccentric drive (18) oscillates the band saw housing (12) and drive mechanism to cause the cutting angle of the blade to vary relative to the work (w) for improved cutting efficiency and blade wear. In another embodiment, a piston (54) is provided in one of the saw guides (46) which alternatively deflects and releases the cutting span of the blade (50) to cause a variation in its angular orientation relative to the work piece (w).

Abstract: A multi-cylinder drying section and method in a paper machine wherein the paper web to be dried is guided into contact with the surfaces of heated drying cylinders wherein the drying fabric is cooled as it travels from one drying cylinder to the next. According to one embodiment, preferably used in the first group or groups of drying cylinders, a single-fabric draw is used wherein the web is supported on the drying fabric as it runs from the cylinders of one line to the cylinders of the other line so that the web is in direct contact with the surfaces of the drying cylinders in one line while the drying fabric is in direct contact with the surfaces of the cylinders in the other line. The drying fabric is cooled as it runs between the cylinders on which the web is in direct contact with the heated surfaces by causing the drying fabric to come into direct contact with a cooling roll or cylinder surface whose contact area is relatively large. In another embodiment wherein the web is conducted through the drying section in a twin-wire draw, i.e., wherein the web travels between the cylinders of the respective lines in an open draw, the drying fabrics come into direct contact with guide rolls which act as cooling members to cool the respective fabrics. The invention provides lower production costs and reduced energy consumption as well as improved machine reliability, a significantly reduced length of the drying section and increased service life of the drying fabrics.

Abstract: The dry end of a paper making machine includes a twin wire dryer group following a single wire dryer group. The paper web is continuously guided by a support belt which moves alternately between dryer cylinders and intermediate deflecting rolls in the single wire dryer group. In the twin wire dryer group, the web travels over open lengths between dryer cylinders in the two rows of the second group. A rope guide threads the web into the twin wire dryer group. The start of the rope guide, called the rope shears, is in the vicinity of the periphery of the last or next to last deflecting roll called the selected deflecting roll in the single wire dryer group. Between the selected deflecting roll at the start of the rope shears and the preceding selected dryer cylinder, there is a relatively long straight path of travel for the support belt. Parallel to that path, there is a scraper and a guide plate which deflects the edge strip of the web laterally into the rope shears which is laterally to the side of the web. The rope guide then threads the web into the second dryer group.
